Nope, it won't save them. That tactic has never worked. Appeasing a potential conquerer has never been a smart thing to do.
Sorry about taking your comment out of context: I thought you were talking about the term WMD as used in the context of Saddam's dirty toys.
As far as the Saddam-sympathizers, I'm reminded of a little quatrain, author unknown:
No one's safe when freedom fails,
And good men rot in filthy jails
And those who cried, "Appease! Appease!"
Are hanged by those they wished to please.
